After being sharpened the blade may be just aseasily returned to its place within the opening 11 and by propermanipulation of the adjusting screw 21, be brought to the desiredposition.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of'tlie same, and thatvarious changes in the shape, size and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the sub-' joined claim.

Having described my invention, I claim: A pencil sharpener of thecharacter de scribed, comprising a handle provided at one end with anenlarged head having a longitudinally extending opening formedtherethrough which has one side wall thereof vertically inclined andprovided with a screw-threaded opening arranged near one side of thelongitudinal opening, a cutting this patent may be obtained for Copiesof five cents each, by addressing the WashingtomD.
